I don't really disagree. Alonso is best utilized in a platoon. You could use him and Santana at 1st, with Santana also playing some OF. Santana would also provide some insurance encase the league adjusts to the "new" Alonso.
Phillips would also be a fit.
OT - what's with the huge K% from Brewers outfielders/prospects? Santana, Broxton, Phillips, Harrison, Diaz...even Brinson. They all strike out a ton!
